Problem is: there is a cost of lowering the dollar. I agree we should but only in conjunction with the following policy: 1. we drill our own oil as much as possible and move to alternate fuels and nuclear/coal energy. 2. we force the government to balance the budget and spend ZERO in deficit, or at the minimum spend only so much in deficit as it can borrow at home and not a penny more.
The problem is, with a weak dollar, oil is much more expensive to purchase and that will grind our economy to a halt. Two, with the government spending $2.5 billion in debt every single damn day, $2 billion comes from foreigners and that means we must continue raising interest rates to continue to attract them to our debt issues which are now worth much less with a weak dollar. Of course every time debt interest rates (coupon rates) go up, the value of old debt becomes much less, but that's a seperate issue.
I have always been a big proponent of nuclear energy. Even the waste can be reprocessed and/or made into depleted uranium for kinetic weapons or plutonium for nuclear weapons (badly needed because of aging stockpile). A nice byproduct of nuclear power is hydrogen. Instead of using recombiners, take it and use it as fuel.
The funding needs to be cut completely from wasteful programs like the NEA, IRS, EPA, UN., etc. That would go a long way into reducing debt.
